I have a question about the IAB sensor on the prelude (JDM 92-96) engine. 1 Does the sensor throw a code if the wiring is not done right? 2 Exactly what needs to be wired if I have an ex 5gen accord? 3 I heard I can simply connect a vacuum hose from the mechanism that opens and closes the secondary butterflies to the IAB and from the IAB to the manifold on any available nipple, also that I do not need to wire up the IAB and can completely by pass the black box. Is this true or is something flawed here. 4 Is the IAB the same thing as the solenoid confused on this? 5 There is a debate on weather or not the secondary butterflies are even needed what do you guys think.
